Abstract

A job site security system contains a wireless communications node and a device such as a tool, a battery, a charger, etc., which contains a controller. Each tool has a locked state and an unlocked state as determined by the controller. Each tool is (initially) in the locked state. When the wireless communications node transmits a signal to the device the controller changes the locked state to the unlocked state allowing the device to be used. A method for securing a job site is also provided.

Claims (39)

1. A job site security system comprising:

at least one device, the at least one device being one of a power tool, a battery pack, or a charger, the at least one device including a first controller operatively-connected to a first wireless transceiver; and

a lockable storage unit including a wireless communication node, the wireless communication node including a second controller and a second wireless transceiver, the second controller configured to:

determine whether the at least one device is located within the lockable storage unit at a time of day defined by a user of the lockable storage unit; and

provide an alert indicating the at least one device is not located within the lockable storage unit at the time of day defined by the user of the lockable storage unit.

2. The job site security system of claim 1 , wherein the alert is one selected from the group consisting of an audible alarm, a visible alarm, and a notification provided to a mobile device.

3. The job site security system of claim 1 , wherein the controller is further configured to determine a signal strength of a wireless signal received from the at least one device is below a threshold to determine whether the at least one device is located within the lockable storage unit.

4. The job site security system of claim 3 , wherein the threshold is set by a user of the lockable storage unit.

5. The job site security system of claim 3 , wherein the threshold is approximately −50 decibels.

6. The job site security system of claim 1 , further comprising:

an electronic lock configured to receive a signal to lock a cover of the lockable storage unit.

7. The job site security system of claim 1 , wherein the second controller is further configured to transmit, if the at least one device is not located within the lockable storage unit, using the second wireless transceiver, a locking signal to the first wireless transceiver of the at least one device.

8. The job site security system of claim 1 , wherein the lockable storage unit is a tool box.

9. A lockable storage unit for storing a plurality of power tools, the lockable storage unit comprising:

a wireless communication node including a wireless transceiver; and

a controller configured to:

determine the end of a working period; and

transmit, upon determining the end of the working period, using the wireless transceiver, a report to a mobile device, the report including at least one of a battery status of at least one of the plurality of power tools or a wear status of the at least one of the plurality of power tools.

10. The lockable storage unit of claim 9 , wherein the report further includes at least one selected from the group consisting of a presence of the at least one of the plurality of power tools, a needed repair of the at least one of the plurality of power tools, and a damage to the at least one of the plurality of power tools.

11. The lockable storage unit of claim 9 , wherein the controller is further configured to:

maintain a data log for tracking which of the plurality of power tools are checked out and where each of the plurality of power tools is located,

wherein the data log is included in the report.

12. The lockable storage unit of claim 9 , wherein the lockable storage unit is a tool box.

13. The lockable storage unit of claim 9 , wherein the controller is further configured to:

determine whether at least one of the plurality of power tools is located within the lockable storage unit by comparing a signal strength of a wireless signal received from the at least one of the plurality of power tools to a threshold; and

transmit, in response to determining the at least one of the plurality of power tools is not located within the lockable storage unit, a locking signal to the at least one of the plurality of power tools.

14. The lockable storage unit of claim 13 , wherein the controller is further configured to provide, in response to determining the at least one of the plurality of power tools is not located within the lockable storage unit, an alert indicative of the at least one of the plurality of power tools not being located within the lockable storage unit.

15. A job site security system comprising:

a wireless communication node;

at least one device, the at least one device being one of a power tool, a battery pack, or a charger, the at least one device including a first controller operatively-connected to a first wireless transceiver;

a mobile device operatively-connected to the wireless communication node, the mobile device including a second controller operatively-connected to a second wireless transceiver; and

a lockable storage unit configured to store the at least one device, the lockable storage unit including a third controller,

wherein the second controller is configured to:

receive, from the first wireless transceiver, a status of the at least one device, the status including at least one of a battery status of the at least one device or a wear status of the at least one device, and

wherein the third controller is configured to:

determine whether the at least one device is located within the lockable storage unit at a time of day defined by an owner of the lockable storage unit.

16. The job site security system of claim 15 , wherein the third controller is configured to:

transmit, with the third wireless transceiver, a report to the mobile device, the report including at least the battery status of the at least one device and the wear status of the at least one device.

17. The job site security system of claim 15 , wherein the status further includes at least one selected from the group consisting of a presence of the at least one device, a repair needed by the at least one device, and a damage to the at least one device.
